26 Claims.

This invention relates to a spindle attachment for a spinning frame and is particularly Well adapted for so-called multiple down ring spinning machines.

In its broader aspects, the invention comprehends a spindle attachment embodying a spindle whirl and brake mechanism so arranged that the spindle whirl can be moved laterally away from the driving belt and the brake concurrently ap plied to the whirl.

In its more specific aspect, the invention comprehends a spindle attachment in which the spindle and whirl move laterally with respect to the belt in a plane perpendicular to the line of travel of the belt, and the lateral movement of the spindle functions to apply the brake in such manner that the further the spindle is moved, the greater will be the application of the brake.

Various types of swing spindle attachments for spinning frames have heretofore been devised, and in such prior art spindles it is usual to provide some braking means for the spindle whirl. The brakes, however, often become worn, and there is lack of uniformity of application of the brake to the whirl. Through the medium of the present invention, the difliculties encountered in the priorart practices are obviated, and a structure is provided which insures the positive application of the brake throughout the life of the device.

Other and more detailed objects will become apparent as the description of the invention proceeds, which description will be given in connection with the accompanying drawing, wherein:

Figure 1 is a detailed plan View of the swing spindle attachment with the spindle removed and parts broken away for clearness;

Figure 2 is a side elevational view taken from the front of the spindle attachment;

Figure 3 is an end elevation taken from the left-hand side of Figure 2; and

Figure 4 is a detailed fragmentary view with parts shown in section.

Referring to Figure 1, the spindle rail is formed in two parallel tubular elements I and 2 which extend longitudinally of the spinning frame in a conventional manner. The spindle attachment is adapted to be firmly clamped in fixed relation to the members i and 2 through the medium of the clamping bolt 3 (Figure 2) and the clamping member 4 adapted to be positioned below the parallel tubular members I and. 2. The upper end of the bolt 3 extends through the fixedly mounted base member 5 as shown at 6. The base member 5 supports all of the operative elements of the spindle and brake. The base 5 is provided at one side with the upwardly projecting flange 1 carrying at the forward side of the base 5 the arm 8 which is provided with a spring seat 9 having the adjustable screw I0 for controlling thedegree of tension placed upon the spring II which functions in a manner hereinafter described.

The opposite end of the base member 5 is provided with a flange I2. The flange I2 carries a bearing pin I3 adapted to pivo-tally support the lower end I4 of a stop motion rod I5. This stop motion rod is designed to have pivotal motion about the pivot bearing I3 in a manner comparable to that of the stop motion rod shown and described in my Patent No. 2,044,621, issued June 16, 1936, to which reference may be made for the detailed character of the stop motion mechanism associated with the rod I5.

Pivotally supported between the flanges I and I2 of the base member 5 is the U-shaped yoke I6. This U-shaped yoke I6 is provided at the free end of each of the legs thereof with an integral upstanding bracket member IT. This yoke I6 is pivotally supported on the base member 5 through the medium of the adjustable bearing member I8 (see Figure 2) having the conical bearing surface I9 fitting into a complementary recess 20 in the yoke and by the similar bearing provided by the screw I3 at the opposite end of the base 5 shown in detail in Figure 4, wherein it will be observed that the screw I3 is likewise provided with a conical bearing end 2| fitting into the complementary recess 22 of the yoke member I6. The screw I3 additionally carries the adjusting nuts 23 for accommodating the pivotal bearing I4 of 3 the stop motion rod I5, regardless of the position of adjustment of the bearing screw I3, and for locking the bearing screw I3 in any particular position of adjustment in the threaded opening 24 of the flange I2. A similar locking nut 25 is provided for locking the bearing screw I8 in any particular position of adjustment with respect to the theaded opening 26 in the flange I.

It will be observed from the foregoing description that the yoke member I 6 is adapted to have a limited rocking movement about a horizontal axis formed by the bearing screws I3 and I8. The right-hand bracket arm H on the yoke I6, as shown in Figure 1, is provided with a seat 26' for one end of the spring II. The spring I I thus functions to press the upperends of the bracket arms I! away from the arm 8 carried by the base member 5 and toward the spindle driving belt 21 of the frame.

The yoke l6 carries a spindle base 28. This spindle base 28 is supported by the complementary bearing screws 29, one of which extends through the top of each of the bracket members H. The bearing screws 29 are adapted to be locked in any position of adjustment through the medium of the locking nuts 31!. It is thus apparent that the spindle supporting base 28 is adapted to have limited rocking movement with respect to the yoke l 6, which in turn is adapted to have limited rocking movement with respect to the base 5. The spindle base 28 is provided with the opening 3| in which the spindle 32 having the conventional whirl 33 is adapted to be clamped through the medium of the spring 34 and clamp nut The spindle base 28 additionally carries the projecting arm 36 adapted to extend into the path of movement of the stop motion rod l5 when the latter is released through the breaking of a thread and swings outwardly about its pivot M.

It will be apparent that when the stop motion rod l5 contacts the arm 36 of the spindle base 28, the yoke it will swing upwardly with respect to the base 5, and the spindle base 28 carrying the spindle 32 will be caused to move laterally away from the belt 2'? to free the whirl 33 therefrom. When the stop motion rod I5 is restored to operative position, the spring H functions to return the yoke I6 to normal position with the whirl 33 in driving engagement with the belt 21.

Coming now to a specific description of the means for controlling the movement of the spindie and for applying the brake to the whirl, it will be observed that the spindle base 28 is additionally provided with a bearing lug 37 (see Figure 3) and that the flange 52 of the base 5 carries a further bearing screw 38. A bearing bolt 39 extends through the bearing lug 31, and a link 40 has its respective ends pivotally mounted on the bearing screw 38 and bearing bolt 39. It will be observed by reference to Figure 3 that the flange 12 of the base member 5, a bracket member ll of the yoke Hi, the spindle supporting base 28, and the link 40 together form a parallelogram, the four corners of which are pivotally connected. The base member 5 and the flange 52 are, however, fixedly secured to the spindle supporting rail and, therefore, the spindle supporting base 28 is adapted to swing toward and away from the belt but is always maintained in a horizontal plane with the spindle 32 carried thereby always in a vertical position.

The spindle base 28 further carries in fixed relation thereto the upstanding arm 4!, which arm is adapted to partake of the same movement as the spindle base member 28. The arm 4i carries at its upper end a bearing bolt 42. A brake member indicated generally at 43 is pivotally mounted on the bearing bolt 42. The brake member 43 is generally U-shaped with one leg 44 of the U extending clear down to the bearing 38 and being bifurcated to accommodate the bearing 38 as shown at 45 in Figure 3. The other leg 46 of the U-shaped brake 43 extends downwardly to a short distance below the pivotal mounting 42 and carries at its lower end the frictional brake contact member 41.

The action of the brake is as follows: When the stop motion rod 15 is released and moves the spindle base 28 laterally with respect to the base member 5, the bearing 42 is likewise moved laterally and downwardly with respect to the base member 5. This movement of the bearing 42 causes the brake member 43 to be moved about the bearing 42, and. because of its relationship to the bearing 38, the brake shoe 4? is adapted to be forced into contact with the whirl 33. It is at once apparent that the greater the movement of the base 28, the greater will be the force applied to the brake shoe ll and thereby to the whirl 33 of the spindle.

Briefly summarizing, the operation of the device is as follows: When a thread breaks, the stop motion rod l5 swings about its pivot l4 and applies force through the arm 36 to the spindle base 28. This swings the upper ends of the bracket arms H of the yoke 56 on the bearing screws 63 and H3. The spindle base 28 in turn rocks slightly on the bearing screws 2%, but this rocking movement is controlled by the link 46 interconnecting the bearing 39 carried by the spindle base 23 and the bearing 38 carried by the bracket base 5, so

that the spindle base 28 moves laterally and downwardly with respect to the base 5 but is always maintained in a horizontal position. This movement of the spindle base 28 likewise effects movement of the brake bearing 42 and applies the brake in the manner above specifically set forth.

From the foregoing detailed description, it will be apparent that the applicant has provided a novel spindle attachment for a spinning frame, through the medium of which the spindle base is swung away from the belt on horizontal rather than vertical pivots, and a structure whereby the brake is positively applied to the spindle whirl through mechanical motion that counteracts the movement of the spindle. It will be additionally observed that the respective bearings are adjustable, permitting slight relative movement be-= tween the respective parts of the spindle attachment and furthermore making it possible to immediately compensate for wear at any time.
